My position regarding the rarity of functional islands for complex solutions in the sequence space is advocated, among many others, by people like @guppio, Meyer, Axe and Gelernter. Would you say that these scholars are irrational?
Regarding this topic, @gpuccio has written a very interesting piece (see below). You may disagree with him, but if you read his piece carefully and without prejudice, you will have no choice but to acknowledge the rationality of his arguments. At the same time, I understand your anxiety, for the stakes are immense. Indeed, if functional islands for complex functions are rare, ID wins and blind, unguided evolution is dead.
